[B]Can vegans stomach the unpalatable truth about quinoa?[/B]
[QUOTE]Not long ago, quinoa was just an obscure Peruvian grain you could only buy in wholefood shops. We struggled to pronounce it (it's keen-wa, not qui-no-a), yet it was feted by food lovers as a novel addition to the familiar ranks of couscous and rice. Dieticians clucked over quinoa approvingly because it ticked the low-fat box and fitted in with government healthy eating advice to "base your meals on starchy foods".

Adventurous eaters liked its slightly bitter taste and the little white curls that formed around the grains. Vegans embraced quinoa as a credibly nutritious substitute for meat. Unusual among grains, quinoa has a high protein content (between 14%-18%), and it contains all those pesky, yet essential, amino acids needed for good health that can prove so elusive to vegetarians who prefer not to pop food supplements.

Sales took off. Quinoa was, in marketing speak, the "miracle grain of the Andes", a healthy, right-on, ethical addition to the meat avoider's larder (no dead animals, just a crop that doesn't feel pain). Consequently, the price shot up – it has tripled since 2006 – with more rarified black, red and "royal" types commanding particularly handsome premiums.

But there is an unpalatable truth to face for those of us with a bag of quinoa in the larder. The appetite of countries such as ours for this grain has pushed up prices to such an extent that poorer people in Peru and Bolivia, for whom it was once a nourishing staple food, can no longer afford to eat it. Imported junk food is cheaper. In Lima, quinoa now costs more than chicken. Outside the cities, and fuelled by overseas demand, the pressure is on to turn land that once produced a portfolio of diverse crops into quinoa monoculture[/QUOTE]
